About Julien

For several years, I have been working with companies and training centers on system administration, networks, cybersecurity, and infrastructure operations.

Through my SystemOps activity, I mainly support VSEs and SMEs on topics related to IT outsourcing, operational maintenance, infrastructure security, and information system resilience improvement.

My missions include:
  • Infrastructure administration and security
  • Deployment of monitoring and backup solutions
  • Access management, network segmentation, and firewalling
  • System hardening
  • Virtualization and automation
  • Documentation and standardization of environments
  • Technical support and skills development for teams
My approach favors reliable, documented, maintainable solutions adapted to the real constraints of companies.
